Kossow is a lifelong resident of Kona who attended Hōlualoa Elementary and Kealakehe Intermediate Schools before graduating from Makua Lani Christian School. While a junior in high school, he earned his Eagle Scout award, and soon after received the Honor of Vigil.

A former Boy Scout lodge-vice chief for Hawai‘i Island, Kossow has served as an assistant scoutmaster with Boy Scout Troop 79, and a section-vice chief for the Pacific Region. He is currently working toward his Bachelor’s Degree in Political Science with the University of Hawai‘i.

“I am proud to be born and raised in this beautiful community,” Kossow said. “I am eager to jump into the conversation and continue the discussion of the current issues that our community is facing such as: creating efficiency in government; pushing for temporary housing for our homeless, working with both County and State agencies to expand the services to those who need assistance; investing in a long-term plan to implement Kona water well security; striving for renewable and alternative energy sources; and enhancing agriculture development for food sustainability.”

Kossow is also a member of St. Michael the Archangel Catholic Church, a former paraprofessional for Aloha Council, and current finance chair for Kona Coast Boy Scouts of America. He is also a game management advisory commissioner for Hawai‘i County District 7, as well as a flight coordinator for Paradise Helicopters.
